On Ubuntu and Debian systems, there are several steps needed:
In server.xml, change the line <Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/>
to have port="80"
.
Install the recommended (not required) authbind package, with a command like:
sudo apt-get install authbind
Enable authbind in the server.xml file (in either /etc/tomcat6
or /etc/tomcat7
) by uncommenting and setting the line like:
AUTHBIND=yes
All three steps are needed.
